The cyberpunks, the Founding Fathers, 19th Century philosophers, and the Enlightenment thinkers - they all looked forward to the world in which we now live, a multimedia psychedelic freakout in which information is free, decentralized, democratized, and easy to access. What they didn't count on though, was that we would choose to keep a whole lot of it out of our heads.

In this episode, we explore a psychological phenomenon called active information avoidance, the act of keeping our senses away from information that might be useful, and that we know is out there, but that we'd rather not learn.

Did Brian Williams lie, exaggerate, or misremember? How certain are you that your most vivid memories are real? How easily could someone implant a false memory into your mind? In this episode you'll learn why psychologists say that your memory is mostly fiction as psychologist Daniel Simons explains how Brian Williams could have easily believed in a detailed war coverage memory that wasn't real, and you'll hear psychologist Julia Shaw explain how she was recently able to easily implant memories into college so that those students would admit to felony crimes that they did not commit.

Is your state of mind from one situation to the next drastically altered by the state in which you live? According to cultural psychologists, yes it is. Studies show that your thoughts, perceptions, emotions, and behaviors in response to a particular setting will reliably differ from those of others in that same setting depending on where you spent your childhood or even where you spent six years or more of your adult life.

On this episode of the You Are Not So Smart podcast, we explore cultural cognition and the psychological effects of the region you call home on the brain you call yours.

My guest this week:

After the interview I try out a cinnamon chocolate cookie and read a bit of psychology news about how reading good books can make you more adept at reading faces.

In this episode we discuss the illusion of knowledge with Christopher Chabris, co-author of "The Invisible Gorilla." After that, we eat a triple-ginger molasses cookie while discussing non-believed false memories.
